As you were working through the example notebooks, and running your training jobs, you may have reviewed the achieved cost savings with Managed Spot Training and seen output similar to the following in your Notebook execution.
Training seconds: 80 Billable seconds: 25 Managed Spot Training savings: 68.8%
In addition to viewing within the context of a Notebook, you can view each training job individually to see the achieved cost savings.
You can calculate the savings from using managed spot training using the formula (1 - BillableTimeInSeconds / TrainingTimeInSeconds) * 100.
For example, if BillableTimeInSeconds is 100 and TrainingTimeInSeconds is 500, the savings is 80%.
